Explanation
NAT (Network Address Translation) is the technology that maps private IP addresses to a public IP address, enabling internal devices to communicate with external networks. When a single public IP must expose all ports of a private IP (essentially a 1:1 static NAT or full port forwarding), NAT is the required mechanism. PAT (Port Address Translation) is a subset of NAT that maps multiple private IPs/ports to one public IP using different source ports, but NAT is the overarching technology. RIP is a routing protocol and ACL controls access - neither performs address translation.
